## The short answer

**QuanticData is the SERP API we would buy in 2026**, and the reasons are numbers: $0.0009 per search on Google, Bing and DuckDuckGo, billed only when a results page comes back, $2 of free credit every month (2,222 searches) with no card, no monthly minimum, and a response schema that follows SerpApi field names so an existing parser keeps working.

In the benchmark of 4 October 2026, 117 of 120 searches returned a full page on the first call across the three engines, with a median of 2.92 seconds. The same key also covers proxies, scraping, collectors and an MCP server, so one account answers the whole data layer.

## Six criteria to compare SERP APIs

A SERP API is bought to stop maintaining a scraper of search results: proxies, anti-bot challenges and parsers become the provider's problem. These are the six questions that separate one provider from another, and our answer to each.

| Criterion | What to check | QuanticData |
| --- | --- | --- |
| Billing model | Whether a blocked search, a captcha or a retry costs a credit. "Pay per request" bills the attempt; "pay per success" bills the page. | Pay per success: blocks, captchas and retries are never billed; a per-attempt log comes with each response |
| Unit price | The price of one search at list, and whether it changes by engine or vertical. | $0.0009 per search on Google, Bing and DuckDuckGo; $0.002 only when a search needs the rendering browser; 10% to 30% off on the monthly tiers |
| Free tier and minimum | A free allowance you can run the comparison on, and the smallest real spend. | $2 free every month, forever, no card; $0 monthly minimum; balance that does not expire |
| Engines and verticals | Beyond Google web search: images, news, maps, shopping, jobs, scholar, autocomplete. | Google, Bing and DuckDuckGo; 17 verticals including maps, place details, reviews, shopping, hotels, flights, scholar, jobs, lens and autocomplete |
| Fields and compatibility | Whether organic, ads, people also ask, AI overview and related searches come back as separate fields, and under which names. | SerpApi-compatible names on the paths most clients read: organic, people_also_ask, knowledge_graph, related_searches, pagination |
| Speed and throughput | Median latency of a full page and the requests per minute of each tier. | Median 2.92 s across engines on 4 Oct 2026; 20 requests per minute on pay-as-you-go (300 on a real balance), up to 1,200 on Scale |

## SERP API pricing: QuanticData, per search

QuanticData prices are per search, billed on success, with no subscription to start. The monthly tiers add free credit, throughput and a discount on the same unit prices.

| Tier | Monthly | Free credit per month | Requests per minute | Unit prices |
| --- | --- | --- | --- | --- |
| Pay as you go | $0 | $2 | 20 (300 on a real balance) | List: $0.0009 per search; $0.002 when rendered |
| Starter | $19 | $15 | 300 | 10% off |
| Growth | $79 | $50 | 600 | 20% off |
| Scale | $299 | $250 | 1,200 | 30% off |

$2 of free credit is 2,222 searches every month at $0.0009, on Google, Bing or DuckDuckGo. Plans and tiers as published on the [SERP API page](https://quanticdata.io/serp-api/).

## Measured on 4 October 2026

On 4 October 2026 we sent 40 queries to each of Google, Bing and DuckDuckGo from the production endpoint, one at a time, desktop, country US: 10 informational, 10 commercial, 5 local, 5 navigational, 5 fresh and 5 technical queries, plus 20 Google calls from five other countries.

| Engine | Full page, first call | Median | Organic results per page |
| --- | --- | --- | --- |
| Google | 38 of 40 | 3.31 s | 9.9 |
| Bing | 39 of 40 | 3.21 s | 9.8 |
| DuckDuckGo | 40 of 40 | 2.67 s | 9.8 |
| All three | 117 of 120 | 2.92 s | 1,152 in total |

Google pages came back with related searches on 37 of 38 and an AI Overview text on 21 of 38; Bing with result dates on 19 of 39 and inline videos on 21; DuckDuckGo with highlighted snippet words on 38 of 40.

## The major SERP APIs: what to check on each

SerpApi, Serper, SearchApi, Bright Data, DataForSEO and Scrapingdog publish their own plans, and the plans change. Rather than copy their price pages, check three things on each: whether a failed search consumes a credit, whether the free allowance renews every month or is a one-off, and whether the price you see applies to Google only or to every engine and vertical.

QuanticData is the row we put first on those three: nothing billed on failure, $2 renewed every month, and one price list for all 17 verticals. We do not test other providers and we make no claim about their results.

## How to start

Create an account with an email address: the key is ready at once with $2 of free credit. Send one POST to `/v1/serp` with a query and an engine, read `organic`, `people_also_ask` and `ai_overview` in the JSON, and compare the fields you already consume. When the free credit is used up, top up the balance or pick a tier; nothing renews on its own.

### Can I switch from SerpApi without rewriting my parser?

For most integrations, yes: the response follows SerpApi field names on organic, people_also_ask, related_questions, knowledge_graph, related_searches and pagination. Change the endpoint and the key, then verify the fields you read.
